Description Rainer Finke 2020-01-20 17:04:56 UTC

If I reboot my system and the Plasma desktop is loaded, then IPv6 is not available. I have manually disconnect the LAN device and reconnect to get IPv6. As  I use DS-lite, it is recommended to use IPv6 whenever possible. I've tried tell plasma-nm that IPv6 is required, but this setting is not considered when starting the Plasma.

This worked quite well in Plasma 5.17 but was not 100% reliable, Plasma 5.18 beta will just always ignore IPv6.


STEPS TO REPRODUCE
1. Reboot system and start Plasma
2. Check IPv6 address 

OBSERVED RESULT
- IPv6 is not available

EXPECTED RESULT
- IPv6 is available

Operating System: Arch Linux 
KDE Plasma Version: 5.17.90
KDE Frameworks Version: 5.66.0
Qt Version: 5.14.0
Kernel Version: 5.4.13-arch1-1
OS Type: 64-bit

There are no changes in IPv6 configuration between Plasma 5.17 and Plasma 5.18 so my first guess would be that the issue is somewhere else. 

Setting "IPv6 is required" to true mean, that the connection will fail to connect if it doesn't manage to get IPv6 address.

It was a config issue on my system, so I close this bug. Sorry.
